Genetic evidence is revealing that human populations began to expand in size in Africa during the Late Stone Age approximately 40,000 years ago. Scientists have found that sub-Saharan populations increased in size well before the development of agriculture. This research supports the hypothesis that population growth played a significant role in the evolution of human [...]

A new diagnostic tool has shown promising results when used with patients of pancreatic cancer, one of the deadliest forms of cancer due to the difficulty of diagnosing it in its early stages. The method, which studies carbohydrate structures in the bloodstream, could lead to the development of blood tests that can detect cancer more [...]

A new study is using advanced single molecule methods to explore processes that lie at the very core of DNA variation in humans. The study focuses on the process of ‘recombination’, which re-shuffles our genetic content at the time of egg and sperm production.

A school-based program that integrates information about healthy relationships into the existing ninth-grade curriculum appears to reduce adolescent dating violence and increase condom use two and a half years later, according to a new report.
Researchers have discovered giant Rydberg molecules with a bond as large as a red blood cell. Determining how Rydberg molecules interact is important because Rydberg atoms are a key ingredient in atom based quantum computation schemes.

Certainly there is strength in numbers, but only if those numbers can effectively communicate with one another. Now, a new study finds that administration of a novel small molecule which effectively disrupts a key bacterial communication process protects an animal host from infection. The research may lead to more effective treatments for bacterial infection that [...]
As a bright, young cheerleader trying out for the high school varsity squad, 14-year-old Laura Jackson had everything going for her. But when a back flip went wrong during a try-out without a trained spotter on hand, Laura landed on her head fracturing her neck and damaging her spinal cord. Laura is now paralyzed and [...]
